Wow, please tell me what settings (weather, time, clouds) you used for the first pic and the pic with the Maserati? Are these screens done with Vanilla Sets?
Your mod looks great, but i like a more soft and smooth look with little grey fog like Kunos standard filter. Could you do such a filter with your white and dark clouds? Would be outstanding ;-)
If you like fog + soft black and white clouds, just try light_clouds from the "soft" set. It looks like what you described.
